“…Popular examples include so-called social logins, such as the ones offered by Google, Facebook, and Microsoft. Their major drawback is the dependency of both the user and the service on identity providers [3] as well as the potential tracking of the usage behaviour [4] to create detailed user profiles. These might become part of data-driven business models such as targeted advertising [5].…”

“…At present, there are only few academic papers on the application of SSI in business scenarios. They include the application of SSI in "know-yourcustomer" processes in banking [7], access to public health services [8], remote management of industrial equipment [3], payback programmes in retail [9], student exchange [10], e-petitions [11], assigning medical information to persons without regular identity, e.g. to fight Covid-19 [12].…”

Self-sovereign identity (SSI) is a new paradigm, which puts users back in control of their own digital identity. This does not only strengthen the position of the users but implies new interaction schemes that may improve interoperability and usability. Smart services systems enable the integration of resources and activities and use smart products as boundary objects. As such systems typically involve digital interactions between multiple actors, it can be assumed that utilising SSI has a positive impact on them. To investigate how these potential improvements manifest themselves, we investigate electric vehicle charging as example of a smart service system. At the core of our conceptual analysis is the service process, which we extract from a reference model. Based on a SWOT analysis, we identify areas for transformation and derive an SSI-enabled interaction model for an electric vehicle charging service. The evaluation of the new process shows that SSI can reduce complexity of integration with partners and can provide a better customer experience through simplified registration and authentication. Moreover, SSI might even lead to the disintermediation of actors in the service system. Although SSI is still emerging, our findings underline its relevance as a mechanism to establish trust in smart service systems through the seamless and standardised integration of digital identities for humans, organisations, and things.

Identity of Things: Applying concepts from Self Sovereign Identity to IoT devices

Identity is a crucial property of Internet of Things (IoT) devices. Due to rapid growth and high numbers of similar devices, reliable identification of those devices is a problem. The origin and history of an IoT device is especially important in security-relevant environments. Our research addresses this issue by proposing an approach based on blockchain and decentralised identifiers (DID). It is inspired by the concepts of self-sovereign identity (SSI) and bootstrapping of remote secure key infrastructures (BRSKI). Devices are equipped by the manufacturer with an identity stored in a trusted execution environment (TEE) and secured by a blockchain. This identity can be used to trace back the origin of the device. During the bootstrapping process on the customer side, the identity registration of the device is updated in the blockchain. This process is performed by a so-called registrar. Smart contracts prevent unsolicited transfer of ownership and track the history of the device. Besides proof of origin and device security our concept can be used for device inventory and firmware upgrade. A prototype implementation was realised to validate the concept. All six use cases have been implemented and tested using an Ethereum blockchain infrastructure. JSON Web Tokens (JWT) have been used as signed artefacts to transfer information between the stakeholders. This enables an asynchronous communication needed for example in an environment with no direct internet access. Such an infrastructure can be provided by an independent association and can be used by all manufacturers. Depending on the environment a registration of devices can be optional or mandatory.

“…To date, the focus of effort in the SSI community has been on personal identity and data privacy for individuals [28], however the underlying computer science techniques can be applied to any type of entity, including digital assets such as datasets [29], and devices [30]. Systems based on the paradigm of the self-sovereignty of human participants, data resources and devices are inherently decentralized, with attributes held at the edges of the ecosystem.…”

Fifth generation (5G) mobile networks will revolutionize edge-based computing by providing fast and reliable network capabilities to remote sensors, devices and microservices. This heralds new opportunities for researchers, allowing remote instrumentation and analytic capabilities to be as accessible as local resources. The increased availability of remote data and services presents new opportunities for collaboration, yet introduces challenges for workflow orchestration, which will need to adapt to consider an increased choice of available services, including those from trusted partners and the wider community. In this paper we outline a workflow approach that provides decentralized discovery and orchestration of verifiably trustable services in support of multi-party operations. We base this work on the adoption of standardised data models and protocols emerging from hypermedia research, which has demonstrated success in using combinations of Linked Data, Web of Things (WoT) and semantic technologies to provide mechanisms for autonomous goal-directed agents to discover, execute and reuse new heterogeneous resources and behaviours in large-scale, dynamic environments. We adopt Verifiable Credentials (VCs) to securely share information amongst peers based on prior service usage in a cryptographically secure and tamperproof way, providing a trust-based framework for ratifying service qualities. Collating these new service description channels and integrating with existing decentralized workflow research based on vector symbolic architecture (VSA) provides an enhanced semantic search space for efficient and trusted service discovery that will be necessary for 5G edge-computing environments.
